Patented Aug. 16, 1938 UNETED STATES rarer orrice 5 Claims.

This invention relates to thread cleaners for removing slubs, knots, lint, snarls, and accumulations of wax-like substances and the like, from thread and yarn, while it is being wound on cones,

5 bobbins or other containers, for use in knitting and winding machines or the like.

The object of this invention is to provide an efficient and improved cleaner, having, among others, the advantages and novel features here- 10 after mentioned, including cleaner members with a much greater range of adjustability for cleaning threads and yarns of different sizes than any I know of at this time, without extra parts.

In the drawing of one embodiment of my in- 13 vention illustrated and described herein:

Fig. l is a front elevation, partly in section for convenience;

Fig. 2, a side elevation;

Fig. 3, a plan, with the standard cleaner members positioned diagrammatically to accommodate a thread two-thousandths of an inch in diameter;

Fig. 4, a diagrammatic arrangement of the cleaner members to receive and clean a thread sixteen-thousandths of an inch in diameter;

Fig. 5, a view of the cleaner disk lower face, showing the apertures that receive the disk-positioning pins; and

Fig. 6, a plan of an additional disk for use in combination with one of the standard disks.

Referring to Fig. 1, my novel thread cleaner comprises a back plate i, with suitable means, such as a curvilinear channel 2, Fig. 2, in its rear face to receive any convenient supporting mem- 35 her, as the rod 3 on the machine, therefor, the plate having at its upper end a locking screw 3, threaded vertically therein for locking the cleaner to its support.

On its front face, the plate carries a cleaner member supporting means, as the bracket 5, which is locked to the back plate as by a suitable screw 6, herein a socket head screw removable by a suitable wrench. The bracket, Fig. 1, is preferably provided with an ample vertical passage 7 at its center, for the thread or yarn to travel in between the upper and lower guides 8, 9, which latter may be of any desired type, for the ready escape of lint, waste, etc.

The bracket member carries two novel thread cleaning members, as disks WA and IBB, each adjustably and fixedly mounted upon the bracket by a suitable locking screw ll, herein of the socket head type, removable by a conveniently fashioned wrench, not shown, which is usually in the care of the overseer, or superintendent of the mill. 52, with apertures 3 at convenient points therein to receive a vertical pin it on the upper face of the bracket 5, to thereby electively and positively position the disk axially against movement however caused, as by insecure looking, or vibration of the machine and floor, which might loosen the screw H. The most minute adjustment, once made, is secure against disturbance.

The cleaner devices at present in use are adjustable to a limited extent only, either longitudinally or by turning them over, to receive thread or yarn of different sizes or numbers. Some of them have additional plates or sets of plates of different sizes, which may be substituted for the original plates, to extend the range of adjustability for different thread sizes, but it is a great inconvenience and expense to be obliged to make such substitutions. In order to increase the range of thread sizes subject to cleaning action by one pair of what may be called standard cleaning devices, to include most of those used by mills today, I have provided novel cleaning disks it, drilled axially to fit accurately the screw ii, and of octagonal outline, each facet E5 of the disk being a different distance from the true center of the disk.

The upper face of the disk carries near its edge and each facet a space-measuring character I! as a numeral, indicating the distance of the facet radially from the true circumference of the disk, or circumference cutting the corners of the facet having the greatest radial measurement, dotted lines, Fig. 3. Obviously, when the disks are in position, Fig. 3, the sum of the two numerals, one on each disk and opposite each other,and identifying certain facets, will give the width of the thread passage l8 between them, measured by any selected unit of measurement, as thousandths of an inch.

Herein, Fig. 3, the left-hand disk has numerals running from naught to seven, and the righthand disk carries numerals extending from two to nine. It will be clear that, by adjusting the right-hand disk only, to position, in succession, the numerals 2 to 9, inclusive, opposite the numeral 0 on the left-hand disk, Fig. 3, eight adjustments may be made, providing electively paths for as many different sizes of thread, for instance, two thousandths to nine thousandths of an inch in diameter, respectively, and by so positioning the disks as to bring together the proper numbers, as 8 on the disk 503 with 2 on the disk I 0A, and then 7 on the disk I BA successively with 4 to 9, inclusive, on the disk MB, the size of the The disk has a circular base section thread path may be extended to 16-thousandths of an inch. Obviously, the numerals indicating the sizes could begin with 3, instead of 2, if desired, or any other number, and extend to a correspondingly higher number.

In many mills today, however, a larger range exists in sizes of thread and yarn used, and by my novel cleaner herein described, with a supplemental disk IDC, Fig. 6, any size say, measured in thousandths of an inch, beginning with two and extending to twenty-five, may be had simply by proper adjustment of the disks. Therefore, to meet the reasonable needs of mills that spin or wind yarn of still larger sizes, or numbers" as they are called, I may provide an additional disk I00, Fig. 6, with facets of proper radial measurement, and bearing numerals from 9 to 16, inclusive. This disk may be substituted, if desired, for the left-hand disk IDA, and then by proper combinations of the numbers on the disks IOC and H113, the consecutive sizes from 17 to 25, inclusive, may be accommodated. For instance, positioning the number 12 on disk I00 opposite number 5 on disk IDB, and successively thereafter with 6, 7, 8, 9, and then the number 16 on disk IGC with 6, '7, 8, and 9, respectively, on disk IUB, the path for the thread may be extended to 25 thousandths of an inch. Clearly, by combining different disks bearing different numbers, an indefinite number of combinations and increased range of sizes may be had.

Furthermore, without enlarging the disks materially, and by making the facets shorter, and thereby the thread cleaning edges shorter, nine or more facets may be provided with increased range of sizes of thread that may be used by each disk.

The great advantage of being able to use threads of practically any size within reasonable limits with one set of disks, only by the proper adjustment of them, is obvious, both with respect to convenience and the expense of the disks.

My invention is not limited to the precise construction shown herein, but may be modified in many details, without departing from the spirit of the claims, and within the scope thereof.

I claim:

1. A thread cleaner comprising a back plate with means for securing it to a support, means including centering members with an opening between them for the discharge of lint, and for supporting cleaner members in axially centered position on the back plate, and a plurality of thread cleaning members axially centered and circumferentially adjusted on said supporting means, each member having a plurality of circumferential facets of different radial measurement adapted to cooperate with a facet on a second similar member thereby to provide between them paths of different widths for the thread; and each facet having an identifying character adjacent to it indicating its distance in stated units of measurement radially from the true cleaner member circumference; means on the cleaner member supporting means and on said member to lock the member to the supporting member.
